Does it really matter how you shuffle, cut an restack the cards?

I do my own method. I shuffle, cut in three piles (left-right) and then I restack the cards from the middle-left. This method seems to work for me. Then, I just draw how many cards from the top according to the spread. ..I don't think it really matters how you shuffle cut and restack the pilles, does it? I know a lot of people have their own methods.
